Analysis of Reagent Purity: commercially available sodium dodecyl sulfate generally contains 1‐dodecanol, 2 which yields a minimum at the CMC in plots of surface tension vs. concentration. The presence of 1‐dodecanol can be detected by an HPLC method. 3 Impurities can also include surfactant homologs and electrolytes, 2 which yield low. The adsorption and structure of sodium dodecyl sulfate (SDS) layers onto positively charged films have been monitored in situ with vibrational sum-frequency-generation (SFG) spectroscopy and surface plasmon resonance (SPR) sensing. Substrates with different charge densities and polarities used in these studies include CaF 2 at different pH values as well as allylamine and heptylamine films. Sodium dodecyl sulfate was chosen as a synthetic surfactant due to the fact that this is a component of many commonly applied products [1, 2]. The aim of this study was to determine surface tension, density and viscosity of aqueous solutions of rhamnolipid and sodium dodecyl sulfate mixture at constant concentration of one surfactant as well as.
